Re: moving some packages back to bookworm stable

[Hans <hans.ullrich@loop.de>]

Doing "apt-get upgrade" will only upgrade all installed packages, but no new 
ones (even, if they are needed).

Better is to do an "apt-get full-upgrade", which will install the whole system 
from stable to testing. However, this might also uninstall some wanted 
packages, thus often it is calles the "intelligent" upgrade. Intelligent does 
not mean, the upgrade is intelligent, but the one doing this upgrade (mostly 
the person, who is root) should be intelligent.

Downgrading is not an easy way, but managable. But it is a lot of intelligent 
work.

How can you do this? This is, how I am figured out (best way for me!)

First, remove the entry from stable off your sources.list.

Then start aptitude and update the list. 

Next manually search all packages you want to downgrade to the needed 
versions. The last apt-get or aptitude log should help.


Mark all installed versions to "remove" (magenta coluur) and needed versions 
to "install" (green colour).

Now, dive manually into all dependencies (these are marked with the red 
coulour)  and do the same as above (mark the installed version first "remove" 
then the correct as "install").

Important: Check that ALL dependencies are correct and no libs or anything 
else is set with red colour.

This process must be done very, very correct! 

After this press "g" (which is for "install now") and if everything was set 
correct, all packages are now downgraded.

Note: If you have missed something, you have to restart again!

>From my experiences this doing so is still faster, than to setup a new system.

Hope this helps.

Good luck!
